Answer 1

You can try this:

string str = "123456789";

           if (str.Length > 5)
           {
             label1.Text = string.Concat(str.Substring(0, 5), "...");
           }
           else
           {
               label1.Text = str;
           }

Answer 2

You can use the insert() method in C# to insert character in any position. Remember it is a zero based index.

string final_data = data.Insert(2,".");

Answer 3

Keep it simple:

string result = data.Insert(2, ".");
